What is FTP?
FTP stands for File Transfer Protocol. It allows you to transfer files to and from the server that your web site is on. To transfer files, you will need a FTP client and a FTP account. The advantage of FTP over downloading files from a web site is that with FTP, you can transfer a whole directory of files at a time, rather than one by one.
What is Anonymous FTP?
Anonymous FTP allows anyone to access a specified directory without a username or password. This means that anyone can access the files in your anonymous directory. Your anonymous directory is public_ftp/.
Configuring Access
